This invention relates general-ly-tozmeans for supportlng auxiliaries onthe shells'of locomotive boilers.

Heretofore, the various brackets for sup:

porting on a locomotive boiler shell, such auX-.

iliaries as air' pumps, feed water-heater pumps, air reservoirs, exter or pipes,etc.,

have been fastened to the boiler shell by studs, which studs have been required to bear the io full weight of the auxiliaries and their brackets, and are consequently subjected to stresses.

in service which frequently produce leaks.

An object of the present invention is to provide means enabling the auxiliaries dise isposed on the outsideoflocomotive boilers to e supported thereon without the use of studs or bolts penetrating the boiler shell. 7

Another object of the present invention is to provide means for supporting on a boiler mi'shell the weight of auxiliaries and their at.-

taching brackets, whereby the studs, or the like, used to fasten the brackets to the boiler shell are not subjected to injurious strains. Other objects of the invention will hereinafter readily appear.

The improvement claimedis fully set forth.-

In the accompanying drawings: Figure 1,

In the practice of the invention referring descriptively to specific embodiments there of which have been selected f reXem lifiCation herein, the boiler shell 10, supports on et 11, and a reverse gear bracket 12; w 5 The feed water heater bracket 11, is formed its opposite sides a feed water heater brack- I hereinafter.

- ets and passing over the top of-the boiler shell,

with a rear wall 11d; curved to fitthe boiler shell, and two parallel vertical end walls 116, which project laterally from the rear wall.

Projectingxlaterally, outwardfrom the top" and the bottom of each end wall is. a lug 110 for the attachment of a feed water heater not shown; A pair of spaced knuckles 11d, project above. the rear wall, and are provided with suitable openings in whiehis fitted a bolt lle, adapted to connect the bracket to a supporting strap. The bracket is fastened to the boller shell by studs 11;, which pass through suitable openings in the rear wall 11a of the bracket and are screwed into the boilershell.

The reverse; gear bracket 12, has a rear wall 120:, curved to fit the boiler "shell, and spaced knuckles 12b, and a bolt 120, similar to those of the feed waterheater bracket 11. It is fastened to the boiler shell similarly to the; feedwaterheater bracket 11, by studs 12 I For relieving the studs 11f and 12d of the feed water heater and reverse gear brackets of the major portion of the weight of the brackets and the attached auxiliaries, a strap 13, connected at each end-to one of the brackis employed. This strap comprises two sections 13a and 136, connected together at their upperendsby a take-up device 130. 'The lower end of'each strap section-is provided with an eye 13d,- di'spose'd between the knuckles of one of thebrackets and receiving the bolt thereof; The upper endof each strap section-is formed with a hook 13e adapted to engage one of the blocks 13g and to lit in a recess13f therein; Each block 13gis provided with two holes 137i, through which pass take-up bolts 132'. Suitable nuts 139' thread.- ed onthe ends of the bolts 132', areadapted to be'adjusted was to draw the upper ends of the strap sections together and thus cause the strap 13 tois'upport on the boiler shell the major portion ofthe weight of the brackets 11 and 12 and the auxiliariesrwhich they carry,.thus relieving thebracket studs of un desirable strains.

the forwardend of Figure 1, and in Figure 3, are shown means similar to those u just described, for-supporting combined runfrom it is secured In Figures 5 and 6, of the drawings, is

5 shown a modified form of construction wherein are employed a strap 15, which passes over the top ofthe boiler shell, and astrap 16, which passes under the bottom of the" boiler shell. The strap 15 is made continuous end to end and has at each enda loop 15a, one connected by a bolt 17 a, to a feed water heater bracket .17, andthe other, by a bolt 18a, to a reverse gear bracket 18. 'l: he strap 16 has an eye 16a, at one end by wh ch to the reverse gear bracket 18 bya bolt 18?). The other end of the strap 16 is provided with a loop 16b,whichengages a U-bolt 17?) attached to the feed water heater bracket 17. Nuts 17c, threaded on the bolt 0 17b, serve as a take-up enabling the straps 15 and 16 to be tightened as desired.

If desired, one or more suitable studs 19, passing through the boiler shell. and slots 19a in the brackets, may be employed to additionally secure the brackets 17 and 18 to the shell. p In Figure 7 of the drawings, is shown another modified form of construction wherein the bracket 17 for an auxiliary, is additionally supported on the boiler shell by a relatively short strap 20, connected at one end by a bolt 17a, tothe bracket 17, and at its other end by a bolt21a, to a hanger bracket 21, secured to the boiler shell by rivets 21?).

In Figure 8 is shown a further modification WlllCll difiers'from that shown in Figures 5 and 6 in that instead of employing the bottom strap 16, the brackets 17 and 18 are respectively, formed with vertical flanges 9 17c and 18d, which are connected by a horizontal bolt 22, having nuts '22aat each end to provide for take-up.

Although supports for certain auxiliaries. have been described, it is to be understood. that the invention is not limitedto such particular auxiliaries, but is adapted for supporting all such'auxiliaries as it may be de sirable to support on the sides of a boiler.

Further, it is within the contemplation of the V invention to fasten the ends of the strap to the auxiliaries rather than the bracket. i

It will be noted that in the foregoing description the term strap has been employed in variousplaces to denote exemplifications 5 0f the hanger referred to in the various claims appended hereto. While the strap formation as shown in the drawings and described in' the-specification is a preferred type of hanger, it will be obvious that if 0strap is understood in its narrower sense as a flat flexible band, hanger is a broader term, and would include not only the strap of such limitation, but also chains, cables,

bars, and the like, that are well-known and of every day use in the capacity of a strap.l

While some of the various forms of construction have been described and shown, it

p is obvious that many variations in procedure,
